Overhead Allocation to Engagements (Indirect Cost)
Apportioning office rent, IT, and support staff costs across client engagements using a standard overhead rate.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Engagement Overhead Cost (Allocated) | Expense (+) | 1,200.00 | - |
| Overhead Pool (Cleared) | Expense (−) | - | 1,200.00 |
💡 Accountant's Note
Indirect costs (office, IT, admin) are pooled and then allocated to engagements using a predetermined rate — often as a percentage of direct labor hours or cost. This ensures each engagement bears its fair share of the cost structure.
Practitioner & Systems Framework
💻 ERP Architecture
The overhead pool is typically accumulated in one or more overhead cost centres (Rent, IT, Finance, HR, Reception) throughout the month. At month-end, a predetermined overhead rate (calculated annually: total budgeted overhead ÷ total budgeted direct labour hours) is applied to actual direct hours worked on each engagement to allocate overhead. If actual overhead differs from applied overhead at year-end, an under- or over-applied overhead variance arises, which is typically expensed to the income statement as a period cost. For government contracting firms (common in consulting), overhead rates must comply with applicable cost accounting standards (e.g., FAR/DFAR in the USA) and may be subject to government audit.
⚠️ Audit Flags
(1) Rate reasonableness — is the predetermined overhead rate based on a realistic budget? An artificially low rate understates engagement costs and overstates profitability. (2) Overhead pool composition — are only legitimate indirect costs in the pool? Costs that are directly attributable to specific engagements should be direct costs, not pooled. (3) Under/over-applied overhead at year-end — a large variance between applied and actual overhead indicates the rate was significantly off, requiring disclosure and adjustment.
